Ye Wanwan could regurgitate the martial competition's rules backward.
For example, even though Meng Tian took out a dagger, a dagger wasn't considered a concealed weapon or poisonous powder, so a weapon like that was permitted. Hence, Meng Tian didn't break the rules, and his guilt couldn't be decided simply based on whether he intended to kill her or not.
Ye Wanwan wasn't dumb. Everyone saw Meng Tian pull out a dagger and attack her during the match but was killed by her instead after she stole his dagger, so why did these higher-ups still determine her to be guilty?
They weren't favoring a certain side; these were Scarlet Flames Academy's rules indeed.
As long as Meng Tian didn't use poison or concealed weapons, the dagger was permitted unless he used his dagger and stabbed her several times, leading to her death. Only then would Meng Tian be punished.
Since they did things according to the academy's rules, this would be easy for her.
